PTFE kana polymer O-Rings ine kupikisa kwakanyanya kunenge ese makemikari anosanganisira asidhi, mabhesi, oiri, chiutsi……
PTFE O-Rings Nhanganyaya
Kusapindirana kwePTFE kune anenge ese magasi uye zvinwiwa zviri pakati -320 °F uye +450 °F ndechimwe chezvinhu zvayo zvinoshamisa kana ichishandiswa muO-Ring sealing systems.Kuvimbika kwePTFE kunozoderedzwa chete kana yasangana neakanyungudutswa alkaline simbi uye mamwe halogenated makomisheni.PTFE ndicho chinhu chesarudzo kuti ive nechokwadi chekuenderana kweO-Ring chisimbiso chine chisimbiso chepakati kana chekuisa chisimbiso pamusoro petembiricha yakakura.
Mazano ekugadzira ePTFE O-Rings
Yakajairwa rubber O-Ring tsika senge Per MIL-G-5514 inowanzo kurudzirwa kana yekumisikidza-mhando yekumisikidza kune ane simba maapplication.TG O-Rings inogona zvakare kushandiswa kune chaiyo maapplication.Sezvo misiyano yenyama yePTFE uye elastomeric makomisheni yakakwira zvakanyanya, inotevera dhizaini uye yekuisa nzira ichaunza yakanakisa yekuisa chisimbiso mhedzisiro maererano nekuita uye chisimbiso hupenyu:
- Kusiyana nerabha O-Rings, PTFE O-Rings haigone kutadza kutenderera, saka zvinogoneka kuderedza hupamhi hwegland.
- PTFE O-Rings haina kuenderana kwerubha O-Rings;saka zvinodikanwa kudzikisa kudzvanya kwepakati-chikamu kunoenderana neyakatsanangurwa yerabha kuitira kurerutsa kusangana.
Kuisa Mazano epolymer O-Rings
Kuchengetedza iyo PTFE O-Rings kubva pakunakirwa kana kugochwa panguva yekuiswa kwakakosha.Gouging inogona kuitika uchitambanudza O-Rings pamusoro pemapfudzi akapinza kana shinda.Inogona kudziviswa nekutakura zvindori pamusoro penzvimbo dzakapinza nekushandisa zvishandiso kana kupa makona emakona kana radii.Kutambanudza zvine mwero, kana zvichibvira pasi pe10%, inokurudzirwa panguva yekuiswa kweO-Ring.Kushandiswa kwemafuta anopisa kana kugeza kwemvura kunofambisa kutambanudza zvakanyanya sezvinodiwa.Dhizaini shanduko kana akakosha maitiro anogona kudikanwa kune akatambanudza mamiriro anopfuura 20%.
PTFE inogara ichikambaira kunge ese thermoplastics.Ichi chimiro chinoda kugadziriswa kuitira kudzivirira kurasikirwa kwechisimbiso mutoro.Zvinogoneka kusimudzira kukanganisa kwekuyerera kwechando nekugadzirisa zviyero sezvakakurudzirwa mumatafura.
PTFE O-Rings inogona kugadzirwa kubva kune akasiyana makomisheni akadai segraphite-yakazadzwa PTFE, bronze uye girazi.Muzviitiko zvakawanda, zvinodikanwa zvinogona kusangana nePTFE isina kuzadzwa.
Zvakanakira zvePTFE O-Rings
- O-Rings ndeimwe yemhinduro dzakakodzera kune yakaderera-kudzvinyirira masisitimu
- Yese kemikari inoenderana yePTFE
- Tembiricha yakakura iri pakati -320 °F uye +500 °F
- Kukurumidza mitengo uye nekukurumidza kutendeuka
- Yakakura saizi kusarudzwa kweO-Rings pakati pe0.110 ″ uye ~ 40 ″;yakakosha saizi inowanikwa pakukumbira
- Vacuum kune high-pressure, kana yakashandiswa pamwe chete neakakodzera back-up ring
